Marketplace API Data: How to Access It

eCommerce marketplaces offer many opportunities for merchants and vendors who provide specialized software for them. The data stored in these marketplaces is of the highest value - access to it allows vendors to propose their software to online sellers with advanced features.

However, for such benefits, it is necessary to establish a data marketplace API integration between software systems and platforms like Amazon, eBay, Walmart, Etsy, etc. Such integration is the cornerstone of a successful B2B software business. It enables software vendors to extend the functionality of their solutions and provide seamless business operations to e-merchants.

Necessary Marketplace Data

Given the importance of data marketplace API integration, it makes sense to question the need for marketplace data in the eCommerce software sphere in the first place.

Marketplaces like Amazon, eBay, Etsy, etc. store data of online shops listed on them. Merchants who build their stores on such marketplaces rely on the marketplace data related to orders, products, customers, categories, and more to run their eCommerce business. Therefore, eCommerce software that provide merchants with a solution to automate their processes need access to such data so that they can perform their core functions.

Important data from marketplaces include customer info (name, address, contact number, email address), product info (id, price, image, description, quantity), order info (order number, order status), etc. This information is necessary for eCommerce software to complete their designated operations.

For example, a data marketplace API integration between multichannel software and, for example, eBay and Etsy will enable data access to their stores. With data related to products from marketplaces, the software can create product lists across multiple channels automatically, without the need for the merchant to manually create the lists on every channel. Accordingly, multichannel software can add, update, and delete product information as required.

API Integration with Marketplaces

Data marketplace API integration is the process of establishing a connection between eCommerce software and various marketplaces such as Amazon, eBay, Etsy, Walmart, etc. Its development allows different software programs to access the data stored in such marketplaces, which is required for their effective functioning.

Such integration allows two applications (eCommerce software and marketplace) to communicate with each other and transfer data with the help of an API.

Moreover, data marketplace API integration is beneficial for software vendors in expanding their clientele. The more marketplaces they integrate with, the more merchants become their prospects. Most of these merchants include international websites, opening doors for the software vendors to get international exposure for their business.

That said, API integration also brings more profits for software vendors. More clients from marketplaces mean more revenue, and hence, higher returns on investment.

However, data marketplace API integration is a tricky process. It involves a lot of challenges, as described below:

  • Integrations cost around 4000 dollars per connection. Added to them are the costs of infrastructure, setup, and maintenance.
  • Integrations are time-consuming, taking around eight weeks to complete one integration.
  • Integrations need advanced developers, difficult to hire and onboard. They also need constant upgrades as the marketplace APIs release their newer versions.
  • Multiple the time, money, and resources needed for one integration to the total number of integrations you are willing to establish.
